Creating Slow Cooker Lasagna is a straightforward process. Follow these easy steps for a guaranteed delicious result:

1. Brown the Meat: In a skillet over medium heat, brown the ground beef or sausage with the chopped onion and minced garlic until fully cooked. Drain excess fat.

2. Prepare the Sauce: Add the crushed tomatoes, Italian seasoning, salt, and pepper to the meat mixture. Stir well and remove from heat.

3. Mix the Cheese: In a separate bowl, combine the ricotta cheese, egg, and half of the Parmesan cheese. Mix until well blended.

4. Layer the Ingredients: Begin layering in the slow cooker:
– Spread a layer of the meat mixture across the bottom.
– Lay down a layer of noodles (break if necessary to fit).
– Spread a portion of the ricotta mixture on top.
– Add a layer of mozzarella cheese.
– Repeat the layering process until all ingredients are used, finishing with meat sauce and a generous layer of mozzarella and remaining Parmesan on top.

5. Cook in the Slow Cooker: Cover and cook on low for 4-6 hours or on high for 2-3 hours, until the cheese is melted and bubbly.

6. Let it Rest: Once cooking is complete, let the lasagna rest for 15 minutes before slicing. This allows the layers to set.

7. Garnish: Top with fresh basil if desired, adding a pop of color and freshness.
